Patent number: 6963678Abstract: A system of reflectors is used to form beam-expanding and collimating electro-optic transducer devices, including radiation sources and/or detectors. Preferably, the reflector system is of the Cassegrainian or Ritchey-Chretien type. Radiation such as light signals can be conducted to or from the transducers by fiber-optic cables. Alignment of optical conductors or “cores” of the fiber-optic cables or the reflector system with a transducer is provided by coupling a magnetic member to the conductor or reflector system and applying a controllable magnetic field from outside of the device to provide alignment, and then fixing the components in place by the use of means such as light-curable epoxy resin.Type: GrantFiled: October 22, 2001Date of Patent: November 8, 2005Assignee: Sanmina-SCI CorporationInventors: Arthur H. Werkheiser, David R. Porter, Ralph Barry Johnson

Patent number: 6795250Abstract: A lenticular lens array for creating a visual effect for an image viewed through the lenticular lens array comprises a plurality of lenticules disposed adjacent to each other. Each lenticule comprises a lenticular lens element on one side and a substantially flat surface on an opposite side.

Patent number: 6741395Abstract: Producing a tool for creating a mandrel for forming elliptically-shaped lens elements of a lenticular lens array comprises the steps of providing a base member having a radius b corresponding to a minor axis of an elliptical shape, the elliptical shape corresponding to a desired elliptical shape for each lens element of the lenticular lens array, and cutting the base member along a plane that forms an angle k with the minor axis of the desired elliptical shape. The elliptical shape comprises a major axis perpendicular to the minor axis, a vertex of the desired elliptical shape lies at a point a along the major axis, and the angle k is given by the formula cosine(k)=b/a.Type: GrantFiled: July 3, 2003Date of Patent: May 25, 2004Assignee: LentiClear Lenticular Lens, Inc.Inventor: Ralph Barry Johnson

Patent number: 6625376Abstract: A system of reflectors is used to form a beam-expanding and collimating terminus and coupler for fiber-optic cables. Preferably, the reflector system is of the Cassegrainian or Ritchey-Chretien type. Alignment of optical conductors or “cores” of fiber-optic cables is provided by coupling a magnetic member to one core end and applying a controllable magnetic field from outside of the terminus to move the core into alignment position, and then fixing the core in place by the use of means such as light-curable epoxy resin. Use of this process in termini, couplers and splices is described.Type: GrantFiled: July 19, 2001Date of Patent: September 23, 2003Assignee: SCI Systems, Inc.Inventors: Arthur H. Werkheiser, David R. Porter, Ralph Barry Johnson

Patent number: 6600855Abstract: Reflections from an air-to-solid interface in a multiple reflector optical device are suppressed by giving the output surface of the device a slightly curved refractive surface so as to deflect the reflections away from the optical axis of the device. The device is shown in use as a transducer input/output device, and as a fiber-optic cable terminus and coupler.Type: GrantFiled: December 10, 2001Date of Patent: July 29, 2003Assignee: SCI Systems, Inc.Inventors: Arthur H.

Patent number: 5910659Abstract: A thermal cell has an infrared source element for producing an infrared signal and a spatial decorrelator element which spatially decorrelates the generated infrared signal to increase the fill factor of the thermal cell. The infrared source element includes an infrared generating cell, with a resistive element. The spatial decorrelator element is disposed above and spaced apart from the infrared source element and has an aperture formed therein and through which the infrared signal radiates. The aperture extends substantially orthogonal to the primary surface of the source element and between primary surfaces of the decorrelator element, which are in turn substantially parallel with the source element primary surface. The side walls of the aperture reflect the infrared signal.Type: GrantFiled: April 30, 1996Date of Patent: June 8, 1999Assignee: The United States of America as represented by the Secretary of CommerceInventors: Ralph Barry Johnson, Michael Gaitan, Ronald C.
